A Conversation With John:
How have you seen bridge engineering evolve over your career, and where do you see it heading next?
I started my career drafting by hand on mylar with pens, long before spreadsheets and advanced software. The changes since then have been significant. Over the past decade in particular, 3D modeling has transformed how we design and deliver projects. It has created efficiencies I never would have expected early in my career.
That said, no matter how advanced the tools become, the fundamentals still matter. You still need to check your work, understand the structure, and make sound engineering decisions. Technology can make us faster, but it can’t replace judgment.
Looking ahead, I think we will see more automation, especially for smaller, more routine structures. There may be opportunities for more standardized solutions. But bridge engineering will always require customization, since each situation is unique. Every site is different, and the larger, more complex structures will always require thoughtful, project-specific design.
You’ve managed large-scale bridge asset programs and complex projects. Which project was the most memorable and why?
The Ravenel Bridge and the bridge asset management program for South Carolina Department of Transportation District 6 stand out. I was recruited in 2010 to help lead that effort, and I’ve been involved with it ever since.
It’s more than just a project to me. I live near the Ravenel Bridge and see it every day. That creates a personal connection. I take the responsibility seriously because these are public assets, and the funding comes from taxpayers, including me. I approach every decision with that in mind.
Over time, the program expanded to include multiple movable bridges across the coastal region, which added another layer of complexity. These structures are some of the most valuable and complex assets the state owns. Managing their inspection, maintenance, and long-term performance has been both a challenge and something I take a lot of pride in.
Tell us about a professional success story that you’re proud of.
One of the things I’m most proud of is being recognized by our client as a trusted advisor for their bridge asset management program.
That level of trust is earned over time. It comes down to doing what you say you are going to do and consistently making decisions in the client’s best interest. In this case, that also means being mindful of how project funds are spent. There are always more needs than available resources, so it’s important to focus on what truly matters for the long-term performance of the structures.
When a client knows they can rely on you to make thoughtful, responsible decisions, that’s a meaningful accomplishment.
“John brings technical expertise, client-focused commitment, and teamwork to every project he works on. For the owners who rely on John for his knowledge of how bridges are designed, constructed, and maintained, and for his GFT teammates, he’s a trusted partner, advisor, and mentor, making him a key contributor to our success across the Southeast.”

Corporate Bridge Practice Leader
How do you mentor and develop the next generation of bridge engineers?
For me, mentorship starts with experience in the field. You can learn a lot from plans and models, but until you see a structure up close, it’s difficult to fully understand its scale, complexity, and how it behaves over time.
I try to get younger engineers out in the field as much as possible so they can connect what they see on paper to real-world conditions. That hands-on experience is critical.
I also believe in leading by example. I’ve always taken the approach that I’d never ask someone to do something I wouldn’t do myself. Whether that’s inspection work, maintenance support, or solving a problem in the field, being involved alongside the team builds trust and helps develop stronger engineers.
What’s something about you that your colleagues might be surprised to learn?
Before engineering, I actually went to culinary school and worked as a sous chef in Philadelphia. At one point, I was told by the head chef I had fileted more than one million Dover sole as part of dinner service preparations. It was a very different environment, but it taught me discipline, attention to detail, and how to perform under pressure. Those are skills that still carry over into my work today.
What’s your favorite way to unwind after a busy day?
I enjoy fishing and golfing when I can, but after a busy workday, I like to keep it simple. I’ll go up to our rooftop deck, have a drink, and watch the sunset over the city. We have a view of the Ravenel Bridge from there, which makes it even more meaningful. After a long day, it’s a great way to step back, relax, and take it all in.
